This is a good book, with a lot of insight for sure. The author offers great examples to illustrate his points and these are relevant, and on the whole, useful. My issue with this book is that, after a while, it becomes a bit of a tedious read. Questions like "would you rather have 5$ today if your mood was mediocre because you just had a stellar glass of chardonay or 15$ if your dog had previously had an epileptic seizure and you had a mild cold." Ok, this is an exaggeration, but there are so many of these types of scenarios that I found myself losing interest in the topic. It's not that the material is bad, or even that it is poorly written. Only that for the layman who just wants a good read it can be, well, a bit boring.
The book is at its best when Kahneman describes real world circumstances and explains our mind rational (or irrationality) for their outcomes. These certainly provide real insights into how the simple mechanisms of our brains (he refers to this as system 1) operate. He contrasts this with our system 2, which is the more rational, though lazy system of thinking. Yet as the book unfolds, he uses these systems to examine very minute operations of these systems that eventually wore me down until I just wanted to activate my system 1 and flip on mindless cable TV.
